Benefits of technology

[0012]It is therefore an object of the current invention to provide a single system and interface for offering convenient and efficient access to heterogeneous data, including e-mail, calendar / date book, spreadsheets and legacy data in proprietary database systems. These terms are commonly known in the art, wherein e-mail represents electronic mail deliverable in a recognized format, including attachments and other electronic mail attributes. Calendar / date book data represents dates of meetings, appointments, holidays, or other noteworthy events maintained in a searchable database type format. Spreadsheets represent financial records and statements in a tabular, electronic format. Legacy data in proprietary database systems includes data stored in relational database systems or other type of database systems such as object-oriented databases or multimedia databases. Access to the information should preferably be provided through a single and simple query interface.
[0016]It is another object of the current invention to provide a central location for enabling a series of users (using various devices) to access information at multiple data sources that may be at the same enterprise or various enterprises. Such a central location should offer a single point of access to the information desired in a robust manner, offer security and maintain access control for information stored in the heterogeneous data sources, and provide for authentication and access tracking.
[0017]It is yet another object of the current invention to provide an interconnection between a central data location and the heterogeneous data sources such that the interconnection can quickly, reliably, and efficiently communicate between the central data location and each data source. Such communication involves transforming the queries and commands that originated from the device to a form that can be accepted and executed by the application programming interface (API) of the individual data source.
[0018]It is a further object of the current invention to provide a remote enterprise architecture that supports queries from and responses to the central data location for use in a multiple user and multiple device data access scheme. The remote enterprise architecture should permit rapid access to the information and transmission of the information while simultaneously maintaining firewall, security, and encryption requirements.
[0019]It is yet a further object of the current system to provide a user interface that can be easily customised by an enterprise. This allows for the maintenance of information or preferences of users. Further, the user interface should preferably provide access to enterprise data via various devices and take into account enterprise and user preferences when interfacing with a user. If necessary, information can be transformed accordingly and displayed to the user.
[0027]It is an object of the current invention to provide a new solution for word processing. This will be achieved by searching for relevant information from remote data sources and allowing the user to paste the search results in an appropriate format automatically. All the advantages of remote information access from the current invention would be applied and add value during the task of word processing.

Problems solved by technology

Problems with providing remote access to heterogeneous information sources are associated with accessing and presenting results from multiple systems.
Problems arise when an individual is searching for a contact phone number urgently.
The problem is worse when the number of matches is large.
The situation becomes worse when a developer is trying to write a program that can access data from heterogeneous information sources, which provide a unique, proprietary API (Application Programming Interface).
However, they only provide a generic API to access these systems without attempting to dispatch the queries and integrate the query results according to the structures or semantics of the data.
Accordingly, although much information is available over the Internet, much of the information is stored in dissimilar systems.
Along with the problem of accessing information from different remote data sources, users frequently have access to different devices, each having different data access and display abilities / requirements.
For example, certain cellular telephone handsets have the ability to receive e-mail, but do not have a built-in word processor to display a Microsoft® Word document.
Certain mobile phone handsets can play music in MP3 format but cannot process songs in WMA format.
Also, many PDAs (Personal Digital Assistants) do not have the ability to edit any document or update enterprise databases, but can retrieve or even maintain personal data, such as emails, calendars and contact address.
However, while most devices are able to display the body of an email properly, most fail to display / render email attachments that may be of arbitrary formats.
Working with data that requires launching multiple applications is cumbersome and tedious, especially on a mobile device.
Due to the limitations of the display of a device, which may impose a limit on the number of applications visible at any one time, the transition from one application to anther is usually not seamless and involves many repetitive steps.
Furthermore, individual applications have unique user interfaces and functionalities that can reduce the productivity of mobile device users.
Further, certain organizations limit and maintain access to the information maintained in an enterprise.

Abstract

A method and system for providing remote access to heterogeneous information sources from computing devices including but not limited to personal computers, laptop computers, PDAs, cellular telephones is presented. A middle-tier server is provided in a multi-tier environment for allowing a data-centric approach to accessing, modifying and updating content located at remote data sources. The middle-tier server provides functionality for a mobile (or similar) user to perform a search query, request for document and / or data, update remote data, and perform commands on remote data sources. In addition, the middle-tier server manages the authentication of the user in sessioned or sessionless mode. In particular, search query results are processed such that the results answer a search query. That is, rather than simply providing a list of document matches, the middle-tier server extracts information from the document that answers the search query most appropriately. Finally, the middle-tier server, using user preferences, device capabilities and settings, transforms the result, document or data into an appropriate format that is suitable for the device, user and communication network. This allows the user to easily process and view the document on a (possibly limited capacity / functionality) device.
